"Figure 8. NEUROLUCIDA reconstructions of biocytin-filled hippocampal CR [Cajal-Retzius] cells. Representative examples of reconstructed hippocampal CR cells filled with biocytin. Their somatodendritic configuration is given either in red or orange, and the axonal domain in blue or green to distinguish between the 2 neurons. The framed area shows the termination of an individual axonal collateral ending in a growth-cone like structures. The characteristic firing patterns of one of the reconstructed neurons is also shown in the corresponding color. ... (B1) Two CR cells, one with its somatodendritic domain (red) in the OML [outer molecular layer] but with a projection of the majority of axonal collaterals (blue) crossing the hippocampal fissure terminating in the SLM [stratum lacunosum-moleculare]. The other CR cell has its somatodendritic domain in the SLM (orange) but with 2 axonal domains (green), one in the SLM and the other in the OML {CA1 Local-Projecting Cajal-Retzius*}. One of the green axonal collaterals (framed white area) terminates with a tuft- like structure in the OML."
